From what I understand from a Perl 6 meeting a couple of weeks ago, it will have a "topic", which allows you to specify a value for the temporary value as its passed in... (ie 

for @list -> $foo; # $foo can now be used in place of $_ for the rest 
+of the block

Also, $foo defaults to read-only, so you have to specificly specify read-write mode.

PS I'm sure I've made a mockery of Allison's speech, so please forgive me. Also, the minutes of our meeting should be up soon at Portland Perlmongers.

Topics and topicalizers are also explained in more detail in exegesis 4.
